Application filed October l, 1902.

I about a center which lcorresponds with the axis of the bunch which is being operated on.

In such machines the carriers for the jaws are so mounted that the weight is substantiallj7 all on oneside of the center around which the 2o jaws turn, so that the jaws instead of being properly balan'ced with respect to their centercof movement are overbalanced. It has been found in practical operation that it isl exceedingly diiiicult to run machines equipped with these overbalanced jaws at high rates of .speed and that, furthermore, when they are so run excessive wear results.

It is the object of Lthis invention to produce an improved machine employing a wrapping 3o jaw or jaws turning about a center which corresponds with the axis of the bunch being op erated upon, the jaws being so located and arranged with respect to this center that they are counterbalanced.

Avfurther object of the invention is to improve the ldevices by which said jaws are operated.

With these and other objects in view the v invention consists in certain constructions and 40 in certain parts, improvements, and combinations, as will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.

Referring to the drawings, which illustrate one concrete embodiment of the invention, 1 indicates the frame of the machine, which may be of any desired construction and configura- This frame serves to support a main camshaft 2, which may be driven in any suit- 6,0 able manner. As shown, it is provided with'- a gear 3, which is in mesh with -a drivinggear 4, which is operated from any suitable source of power.

In the machine which has been selected for the purpose of illustrating the invention the f wrapping is accomplished by two pairs or sets of wrappingjaws, which are distinguished from the jaws of prior machines employing wrapping-jaws by the fact that. in this machine the jaws are counterbalanced, so as to reduce the inertia of the parts, thereby malrying it possible to run the machine at higher speeds and also to greatly reduce the friction and wear. It will be understood, however, that while the machine shown employs a plurality of jaws the invention includes machines in which thewrapping is effected by a single jaw properly counterbalanced, said jaw having suitable coperating wrapping means co- 8O acting therewith.

The construction by which the jaws are mounted so as to be counterbalanced may be varied widely.v As shown, there is mounted in the frame a support 5, on which are mount- 8 5 ed two carriers 6 and 7. The carrier 6 is provided with a bearing 8, which surrounds the support and with abearing 9, which also surrounds said support. The-carrier 7 is provided with two similar bearings lO and 1l, which also 90 It willbe seen by referring more especially to Figs. 6, 7, 9, and l() that the carriers 6 and 7 have two wings or extensions, one wing or extension lying on one sideof the support 5 and the other lying` 95- on the other side of said support. These wings are constructed so that the carrier as a l tion, As shown, the slide 20 is provided with whole is exactly counterbalanced, the weight on each side of the support being equal.

The wrapping-jaws are supported in the carriers, the construction by which this is effected being of any suitable description. As shown, the carrier 6 is formed with wings in which are mounted slides 12 and 13, and the carrier 7 is provided with similar ways, which support slides 14 and 15. The forward end of each slide is given an angular bend to provide a wrapping-jaw, and to the projecting' portions thus formed manipulator-lingers are secured, thus forming wrapping-jaws. The wrappingjaw on the slide 12 is marked 16 and that on the slide 13 is marked 17. Similarly the jaw on the slide 14 is marked 18, and the jaw on the slide l5 is marked 19. r1`hese Wrapping-jaws are so arranged as to inclose a space which corresponds in configuration to the bunch to y be wrapped, and as usual in this type of machines the space is so arranged that the axis of the bunch corresponds to the axial line of the support 5 on which the carriers which support the jaws are mounted. The several slides and Wrapping-jaws are so arranged that the jaws and slides of each pair counterbalance each other.

. `As usual in this type of machines, the jaws of each pair are given a movement toward and away from each other and from the axial center of the bunch to be wrapped, the movements being so timed that one pair of jaws moves in and seizes the bunch as the other pair of jaws retreats therefrom. Inasmuch as in the present machine the jaws are carried on slides, this to-and-fro movement is effected by moving the slides. The construction by which the movement of the slides is effected may be widely varied. As shown, the slide 12 has overlying it a slide 20, said slide having in engagement therewith the arms' 21 of two bell-cranks 21 22, which are pivoted at 23 to the carrier 6. The arms 22 of these bell-cranks are in engagement with the slide 12. It is apparent that by giving the slide 2O a reciprocating motion the slid-e 12 will also be given a reciprocating motion at right angles to the movement of the slide 20 and that this movement will give the jaw carried by the Aslide 12 a movement toward and away from the corresponding jaw, which is carried by the slide 13, said slide being the slide which is mounted in the other end of the carrier 6. rlhe slide 13 is moved by means of a slide 24, which is similar in all respects to the slide 20, the connecting' bell-cranks being also similar. The slide 14 is moved by a slide 25 and the slide 15 by a slide 26. lhe construction intermediate the slides 25 and 14 and between the slides 26 and 15 is the same as that which has just been described, and a further description is therefore unnecessary.-

The movement of the slides 20, ,24, 25, and 26 may be effected by any desired construca cam-roll 27, and the slide 24 is provided with a cam-roll 28, these rolls being arranged to engage a cam 29, which is loosely mounted on the support 5. Similarly the slides 25 and 26 are provided with cam-rolls 30 and 31,

' these rolls being in engagement with a cam 32, which is mounted on and secured to a long hub 33, extending from the side of the cam 29. These cams 29 32 are so timed that the corresponding movements of the slides produced thereby take place alternately, so that one pair of jaws is moved in to seize the bunch asthe other is moved out to release it.

It frequentlyhappens in wrapping cigars that the bunches vary in size. If, therefore, the movement of the jaws toward the bunch was unvarying, the operation of the jaws on the bunch would be unequal. Means are therefore preferably providedfor permitting the jaws to yield slightly, if necessary, as they come in Contact with the bunch. The means by which this yielding movement is accomplished may be varied in construction. As shown, the cam 29 is provided with a yielding operating side 29', said side being held in position by means of a spring-disk 34. Similarly the cam 32 is provided with a yielding side 35, which is held in positionv by means of a spring-disk 36. The cams are so arranged that the jaws will Yoperate without yielding upon a bunch of the smallest size,

and in case a larger bunch is to be-wrapped the jaws will yield according to the diameter of the bunch. The cams 29 and 32 may be driven in any desired manner. As shown, the cam 29 has secured thereto a gear 37, which is in mesh with an idle gear 38, said gear beingin mesh with a gear39, which is mounted on the main cam-shaft 2.

In order to produce the wrapping movement of the jaws, it is necessary in the machine shown to give the carriers a swinging movement about the center on which they are mounted. This may be eii'ected in any desired manner. As shown, the carrier 6 has secured thereto an arm 40, which has on its end a cam-roll which engages with a camgroove 41 in a cam-disk 42, mounted on the shaft 2. Similarly the carrier 7 is provided with an arm 43, the cam-roll of which engages with a cam-groove 44 in the opposite side of the cam-disk 42. These cam-grooves are so arranged that the swinging movements of the carriers take place in opposite directions, so that one set of jaws is executing its Wrapping movement while the other set is opened and being returned for a fresh grip on the bunch. Means are also provided for opening the jaws in order to discharge a wrapped bunch and also to enable them to receive la fresh bunch to be wrapped. These means may be varied widely in construction. As shown, this is accomplished by giving the cams 29, and 32 a movement. To accomplish this, there is shown a plunger 45, which extends through the support 5, said support being bored out for this purpose. This plunger is connected by` means of a pin 46 to a loose collar 47, which bears against the hub of the cam 29.. The outer end of the plunger 45 is connected to a lever 48, pivoted at 49 to the frame of the machine and having connected thereto an operating-rod 50. This rod 50 is in turn connected to a lever 51, which is pivoted at 52 to a bracket on the frame of the machine, said lever having a cam-roll 53, which engages with a groove in a cam 54, mounted on a cam-shaft 55, suitably mounted in the frame of the ma- The driving means for this cam-shaft has been omitted in the interest of clearness.

While the construction which has just been described constitutes a preferred embodiment vof the invention, it is to be understood that the invention may be embodied in constructions which differ widely therefrom. It is also to be understood that certain features of the invention are capable of use independently of the other features and of use in machines in which the wrapping-jaws are not counterbalanced. Furthermore,'while the machine iny which the invention is shown as embodied is intended for wrapping cigars it is to be 4understood that machines embodying the invention are capable of use for other purposes than wrapping cigars. The invention is not therefore to be limited to the specific form of' construction described or to described.
